Description

A kind of backlight
Technical field
This utility model is related to field of backlights, more particularly, to a kind of backlight.
Background technology
Operationally, its LED lamp bar can generate heat the backlight of liquid crystal display, and inside backlight, relatively airtight structure is led Cause that heat dissipating state is bad, heat cannot timely dissipate for a long time, can lead to the blooming pieces such as diffusion sheet on light guide plate because High temperature deforms upon, for example, slightly heave, and then affects the image quality of display;And the long-time hot operation of lamp bar, can make The life-span of liquid crystal display reduces, and the life-span of led also can be impacted.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of backlight.The structure letter of this backlight Single, cost is relatively low, and heat dispersion is good, quickly the heat that led produces can be dispersed into the external world, and display performance is good, is difficult Damage.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of backlight, including framework and light guide plate, the incidence surface of described light guide plate and the frame being arranged in described framework It is provided with some led, described some led are connected with fpc, and one end of described fpc extends to described light guide plate, and glues between frame side It is attached to described light guide plate away from the side of exiting surface;The other end of described fpc extends to outside described framework, and is pasted onto described On the bottom surface of framework;Described fpc is covered with fin away from the side of described some led.
Further, described fin is graphite flake.
Further, described light guide plate is provided with reflector plate away from the side of exiting surface.
Further, described reflector plate covers the region that described fpc is located.
Further, the region that described fpc is located avoided by described reflector plate.
Further, described fpc is covered with layers of copper away from the side of described some led.
Further, the exiting surface of described light guide plate is provided with least one blooming.
Further, described framework is provided with brake sack.
This utility model has the advantages that the structure of this backlight is simple, and cost is relatively low, by by fin and Fpc is arranged on the bottom of backlight, and on the premise of the display performance not affecting backlight, the area realizing increasing fin comes Improve the heat dispersion of backlight, quickly the heat that led produces can be dispersed into the external world, display performance is good, is hardly damaged; The layers of copper at the fpc back side can also improve the heat dispersion of backlight further.
Brief description
The embodiment one of the backlight that Fig. 1 provides for this utility model;
The embodiment two of the backlight that Fig. 2 provides for this utility model;
The schematic rear view of the fpc of the backlight that Fig. 3 provides for this utility model.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is described in detail.
As illustrated in fig. 1 and 2, a kind of backlight, including framework 1 with the light guide plate 2 that is arranged in described framework 1, described leads It is provided with some led 3, described some led 3 are connected with fpc 4, described fpc 4 between the incidence surface of tabula rasa 2 and framework 1 side One end extend to described light guide plate 2, and be pasted onto described light guide plate 2 away from the side of exiting surface;Described fpc's 4 is another Hold and extend to outside described framework 1, and be pasted onto on the bottom surface of described framework 1;Described fpc 4 is away from the one of described some led 3 Side is covered with fin 5.
Due to described fpc 4 and fin 5 being arranged on the bottom of backlight, the size of described fin 5 will not The display effect of backlight is impacted, by way of therefore, it can the area by increasing described fin 5, to improve the back of the body The heat dispersion of light source.
Preferably, described fin 5 to extend around and be covered in described framework 1 bottom surface on.
Preferably, described fin 5 is graphite flake.
Preferably, described fpc 4 passes through sticking double faced adhesive tape on described light guide plate 2 and framework 1.
Described light guide plate 2 is provided with reflector plate 6 away from the side of exiting surface.
Specifically, as shown in figure 1, described reflector plate 6 and fin 5 are adhered together, and will be described anti-by double faced adhesive tape Penetrate piece 6 to be pasted onto on the bottom surface of described framework 1, wherein, described reflector plate 6 covers the region at fpc 4 place, described fpc 4 Indirectly transferred heat on described fin 5 by described reflector plate 6;Or, as shown in Fig. 2 described reflector plate 6 and radiating Piece 5 is adhered together, and by double faced adhesive tape, described reflector plate 6 is pasted onto on the bottom surface of described framework 1, wherein, described reflection Piece 6 avoids the region at fpc 4 place, and described fin 5 is covered in described fpc 4 and framework 1 near one end of described fpc 4 Bottom surface on, described fpc 4 directly transfers heat on described fin 5.
Preferably, as shown in figure 3, described fpc 4 is covered with layers of copper 9, described layers of copper 9 away from the side of described some led 3 The heat dispersion of backlight can also be strengthened, described layers of copper 9 can be a monoblock, if described fpc 4 back side is furnished with circuit, Described layers of copper 9 can also be divided into some pieces, to avoid circuit.
It is additionally provided with some bloomings 7, the backlight in the present embodiment is in described light guide plate on the exiting surface of described light guide plate 2 Diffusion barrier 71, lower bright enhancement film 72 and upper bright enhancement film 73 are sequentially provided with 2 exiting surface naturally it is also possible to adopt other types or number The blooming of amount, or do not set blooming, should not be limited with the present embodiment.
Described framework 1 is provided with brake sack 8.
Embodiment described above only have expressed embodiment of the present utility model, and its description is more concrete and detailed, but simultaneously Therefore the restriction to this utility model the scope of the claims can not be interpreted as, as long as institute in the form of equivalent or equivalent transformation The technical scheme obtaining, all should fall within protection domain of the present utility model.
